Transactions are central to performance; choosing the right isolation levels and minimizing transaction duration is vital. Memory Management: Performance killer: GenerationType

Connection management and pooling Efficient connection management is foundational. Use a production-grade pool (HikariCP recommended for low latency). Tune pool size to match application concurrency and DB capacity; oversizing wastes resources and undersizing causes queueing. Avoid opening/closing connections per operation; rely on container or library-managed pooling. Avoid opening/closing connections per operation

: The most substantial part of the book, it explores how to use ORM frameworks effectively without sacrificing performance. Key topics include efficient mappings, entity state transitions, and read/write optimizations.
